Campanula plant named &#39;PTDB141302&#39;

ABSTRACT

A new and distinct  Campanula  plant named ‘PDB141302’, characterized by its compact, upright to spreading and uniformly mounding plant habit; freely flowering habit; dark violet-colored flowers; and good container and garden performance.

Botanical designation: Campanula portenschlagiana.

Cultivar denomination: ‘PTDB141302’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct Campanula plant,botanically known as Campanula portenschlagiana and hereinafter referredto by the cultivar name ‘PTDB141302’.

The new Campanula plant is a product of a planned breeding programconducted by the Inventor in Twello, The Netherlands. The objective ofthe breeding program is to create new compact and freely-floweringCampanula plants that have good container and garden performance.

The new Campanula plant originated from a cross-pollination in August,2012 of a proprietary selection of Campanula portenschlagiana identifiedas code number PTDB-1200201S-PT, not patented, as the female, or seed,parent with a proprietary selection of Campanula portenschlagianaidentified as code number PTDB-13001103S, not patented, as the male, orpollen, parent. The new Campanula plant was discovered and selected bythe Inventor as a single flowering plant from within the progeny of thestated cross-pollination grown in a controlled greenhouse environment inTwello, The Netherlands in July, 2013.

Asexual reproduction of the new Campanula plant by terminal vegetativecuttings in a controlled greenhouse environment in Twello, TheNetherlands, since November, 2013, has shown that the unique features ofthe new Campanula plant are stable and reproduced true to type insuccessive generations.

SUMMARY OF THE INVENTION

Plants of the new Campanula plant have not been observed under allpossible combinations of environmental conditions and culturalpractices. The phenotype may vary somewhat with variations inenvironmental conditions such as temperature and light intensitywithout, however, any variance in genotype.

The following traits have been repeatedly observed and are determined tobe the unique characteristics of ‘PTDB141302’. These characteristics incombination distinguish ‘PTDB141302’ as a new and distinct Campanulaplant:

-   -   1. Compact, upright to spreading and uniformly mounding plant        habit.    -   2. Freely flowering habit.    -   3. Dark violet-colored flowers.    -   4. Good container and garden performance.

Plants of the new Campanula differ primarily from plants of the femaleparent selection in the following characteristics:

-   -   1. Plants of the new Campanula are more compact than plants of        the female parent selection.    -   2. Plants of the new Campanula flower earlier than plants of the        female parent selection.

Plants of the new Campanula differ primarily from plants of the maleparent selection in the following characteristics:

-   -   1. Plants of the new Campanula are larger than plants of the        male parent selection.    -   2. Plants of the new Campanula and the male parent selection        differ in flower color as plants of the male parent selection        have light purple-colored flowers.

Plants of the new Campanula can be compared to plants of Campanulaportenschlagiana ‘Blue Planet’, not patented. In side-by-sidecomparisons conducted in Twello, The Netherlands, plants of the newCampanula differ primarily from plants of ‘Blue Planet’ in the followingcharacteristics:

-   -   1. Plants of the new Campanula are more compact and more upright        than plants of ‘Blue Planet’.    -   2. Flowers of plants of the new Campanula are darker in color        than flowers of plants of ‘Blue Planet’.

DETAILED BOTANICAL DESCRIPTION

Plants used for the aforementioned photographs and following descriptionwere grown in 10.5-cm containers during the spring and summer in aglass-covered greenhouse in Poeldijk, The Netherlands and under culturalpractices typical of commercial Campanula production. During theproduction of the plants, day temperatures ranged from 18° C. to 28° C.,night temperatures ranged from 14° C. to 20° C. and light levelsaveraged 6,000 lux. Plants were twelve weeks old when the photographsand description were taken.
